Study Notes
General Aspects of System Design
- Identifying the purpose and scope of the system aligns it with the company's goals.
- User requirements are essential for ensuring the system meets the needs of its intended audience.
- Feasibility study should assess the technical, economic, and operational feasibility of the proposed system.
- System architecture defines the overall structure and components of the system, choosing an appropriate architecture like client-server or peer-to-peer for desired performance.
- Data design determines the database and data storage mechanisms for the system, ensuring data integrity.
- Input and output design specifies the methods for data entry and output formats for information presentation, incorporating user interface design for enhanced experience.
- Processing logic involves algorithms and processing rules for data transformations and business rules, optimizing for accuracy and speed.
Logical File Subsystem
- The logical file subsystem focuses on the organization, access, and maintenance of structured data based on business needs.
- It ensures efficient data retrieval and manipulation.
System Architecture
- The architecture of a system refers to its overall design and structure, encompassing hardware, software, networks, and other elements.
- This structure allows different components of the system to interact with each other to achieve its objective.
- System components include hardware (servers, computers, storage devices), software (applications, operating systems), and networks (communication infrastructure).
- Different types of system architectures exist, such as client-server, peer-to-peer, layered, and microservices.
- Key design principles for a good system architecture include modularity, scalability, reliability, interoperability, communication protocols, data storage and management, security considerations, performance optimization, fault tolerance and recovery, user interface design, documentation, and evolution and adaptability.
Documentation of the Latest System
- Documentation of the latest system helps ensure clarity and transparency for stakeholders, providing a valuable resource for understanding, maintaining, and evolving the system throughout its lifecycle.
- This documentation includes information about: system overview (purpose, scope), system architecture (diagrams, component descriptions), code number system (structure, code assignment rules), logical file subsystem (entity-relationship diagrams, file descriptions), security and audit (security policies, audit trail documentation), computer scheduling of work (scheduling policies, scheduling algorithms), cost and savings analysis (cost breakdown, saving projections), and contact information (support, owners).
Conclusion
- To successfully design and implement the latest system, a holistic approach is needed encompassing general aspects, code numbering, logical file subsystems, system architecture, audit and security measures, computer scheduling of work, and considerations of savings and cost.
- Adequate documentation is essential for transparency and maintenance.
- This comprehensive approach ensures efficiency, security, and adaptability in the evolving landscape of information systems.
